摘要
文章以大丰市为例,探讨了城市生态健康的内涵及评价方法。研究中综合运用压力-状态-响应(PSR)模型和模糊数学方法,评价了具有复杂特性的城市生态健康问题,对城市生态健康评价的研究工作做出了有益尝试。文章采用基于PSR模型的城市生态系统健康评价方法,建立了影响城市生态系统健康各要素之间的联系,并结合模糊数学方法,较好的解决了生态健康评价标准的问题。研究结果表明,运用PSR模型将各种要素联系起来并考虑它们之间的相互作用,可以实现对城市生态系统健康的综合评价。
The connotation and assessment method toward urban ecological health was discussed. A case study on Dafeng City, Jiangsu Province follows integrating with multidiscipline methods such as fuzzy assessment model and press state response （PSR） model. Urban ecological health problem on complex city with many diseases was assessed, and beneficial attempt to urban ecological health assessment in future was described. Based on PSR model for evaluation of urban system health, the links between all elements of ecosystem health and fuzzy method were established, and a better solution for evaluation standard of ecological health was also available. Results showed that the model which links various factors and considering interactions is helpful to achieve a comprehensive evaluation for urban ecological health.
